BURNER.

Application filed January 25, 1924. Serial No. 688,382;

My invention relates toburners more particularly to vapor and gaseous fuel burners.

My invention provides a burner head llit'f ing a main orifice for passing the gas centrally therethrough and the head is further provided with a pie-heating chamber in which a small portion of the fuel is burnt to heatthe main orifice through itpasses to the burner end of the head. I provide a convenient pilot about the critics to properly ignite and distribute the flame.

In the accompanying drawing constituting a part hereofv and in which like reference characters designate like parts:

Fig. 1 is a vertical sectional view of a burner head embodying the principles of my invention, and

Fig. 2- is an end elevational view of such burner showing the general shape of the pilot which is disposed around the orifice.

Referring to Fig. 1, the burner head therein illustrated comprises a sleeve or tubular member 1 having a constricted rear end portion 2 which is provided with an in let opening 3. The expanded or enlarged end of the member 1 is provided with an in ternal screw thread l which is adapted to engage a correspondingly threaded outer body portion of a sleeve 5 to permit adjustmentof the end 6 of the sleeve 5 relative to the shoulder 7 of the sleeve 1. The member 5 is provided with air openings 8 and a plurality of perforations 9 that communicate with the space provided between members 1 and 5.

A cylindrical as delivery or feed pipe 10 having a flanged end 11 constituting its base and a flanged portion 12 near its opposite end. which constitutes a baffle wall, is secured in the sleeve 5 as shown. The pipe 10 is provided with a main orifice or central opening 18 which terminates in a constricted discharge opening 14 at its extreme end, and a plurality of perforations or ports 15 communicating with the end chamber 16 of the burner head. A distributor 17 Fig. 2, is disposed within the chamber 16 around the ipe 10 to uniformly distribute the flame of the gas around the end of the nozzle 18 to improve the combustion of the fuel. A ring member 19 is disposed around the outer surface of the sleeve 5 to reinforce the end of the burner.

The function of the burner head is briefly as follows: The constricted end 2 is connected in any suitable manner to a supply line leading to a supply of vapor or gaseous fuel, said line having means for regulating the flow in accordance with the volume of fuel required. The member 5 may be adjusted by rotating the same to advance the body against, or away from, the shoulder? to reg ulate the inlet opening communicating with the space between the sleeves 1 and 5. The flowing through this inlet opening is admittedthrough the perforations 9 into the combustion chamber around the pipe 10. It will be readily understood that in the combustion chamber may be ignited by inserting a lighted match through the open ings 8.

The burning of a gas in the combustion chamber heats the member 10 to prc-heat gas passing toward the opening The flow of gas through the pipe 10 is retarded by the constricted opening 14 of the nozzle 18, and some of the gas flows through the ports 15 into the chamber 16 where it takes the form of an annulus encircling the pipe 10. As this annulus of gas flows outward, it passes through the distributor 17 and it is broken up into a number of small streams which are distributed about the main gas stream delivered through the discharge opening 14. In this manner, the desired mixing of heated gas with the air may be effected to aid combustion.

By means of the adjustment for regulating the flow of gas into the pro-heating chamber, the main delivery pipe 10 may be heated to any desired degree within limits, to vary the temperature of the pro-heated gas delivered from the nozzle 18. The advantage of this preheating feature is obvious since it materially aids in the combustion of the gaseous fuel.

It is evident from the above description of my invention that a burner head made in accordance therewith provides an efficient and economic burner for liquid or gaseous fuel and further provides a simple and inexpensive device which is readily adjustable to various kinds of uses.

Although, I have ClGSCIll'JQCl' lspecific embodiment'of my inventionit Will be obvious to those skilled in the art that various mot ifications may be made in-the details of construction Without departing from the principles herein set forth.

I claim as my invention 1. In a burner, in combination, a fuel pipe provided With a fuel discharge for delivering fuel for burning, spaced annular plates carriedby the pipe, a sleeve disposed on the annular plates for forming a combustion chamber for the burning of fuel to heat the pipe, said sleeve having perforations therein for air and fuel, a second sleeve for receiving the first sleeve to form a fuel channel to supply fuel to the combustion chamoer through said fuel perforations, said sleeves being adjustably connected thereby to provide for the control of the flow of fuel to the combustion chamber.

2. A burner comprising, in combination, a tubular member having an enlarged end, a sleeve provided With perforations for air and fuel mounted in the tubular member, said sleeve being spaced from the tubular member to provide a fuel channel, a fuel pipe having a discharge opening for delivering fuel for burning mounted in the sleeve,

annular plates for supporting the fuel pipe combustion chamber communicating with the fuel channelthrough the perforations in the sleeve, sald sleeve being ad ustable in the 'tubular member to control the flow of fuel to the combustion chamber, and means for spreading the flame at the discharge opening.

A burner comprising, in combination, a tubular member having an enlarged end, a sleeve provided With perforations for air and fuel mounted in the tubular member, said sleeve being spaced from the tubular member-to provide a fuel channel, a fuel pipe having a discharge opening for delivering fuel for burning mounted in the sleeve, annular plates for supporting the fuel pipe in the sleeve, said sleeve and plates being adapted to form a combustion chamber for the burning of fuel to heat the pipe, said combustion chamber communicating with the fuel channel through the perforations in the sleeve, said sleeve being adjustable in the tubular member to control the How of fuel to the combustion chamber, and a corrugated distributor disposed adjacent the discharge opening to improve combustion.

In testimony whereof, I have hereunto subscribed my name this 17th day of Janu ary 1924:.
